Your gonna blow up your motor the way your running it.
Ditch the fmu, get the 460cc rx7 injectors the 5sfte guys use, an safcII, and a 2 bar map sensor outta a 90-93 alltrac or mr2t.

the stock MAP sensor is behaving exactly like it should. its seeing boost and its not supposed to so it shuts down the ECU. you need a piggyback like the mentioned AFC or the AEM FIC that can take the stock signal and manipulate it and fool the ECU.
